Homeowners that trust Black Bear Basements
I couldn’t be happier with the work Brian Rowles and the team at Black Bear Basements did finishing my basement. From start to finish, Brian was professional, responsive, and extremely easy to work with.
The quality of the workmanship was outstanding, and the entire project was completed on time and on budget, which is unfortunately not something you can always count on with a renovation project. Brian did an excellent job communicating throughout the process, addressing questions promptly, and making sure the work was done right.
What impressed me most was the professionalism and attention to detail throughout every aspect of the project. The finished basement looks fantastic, and the quality of the work exceeded my expectations.
I would highly recommend Brian Rowles and Black Bear Basements to anyone considering a basement renovation. It was an excellent experience from beginning to end.
K Murray
We had a fantastic experience with Black Bear Basements and couldn’t be happier with our finished basement! From the beginning, we were impressed by the personal touch. Brian took the time to meet with us several times before the project started to review the plans and finishes, and make sure everything was exactly what we wanted.
Brian was on-site nearly every day, coordinating the contractors and making sure the project stayed on track. Communication throughout the entire process was excellent, and we always felt informed and confident that our project was in good hands.
The finished product exceeded our expectations and we love the space he created for us. We highly recommend Black Bear Basements to anyone looking for a contractor who is hands-on, communicative, and genuinely cares about delivering a great result!

From start to finish, Brian made the entire experience feel stress-free. He was responsive, thorough, and made sure every detail was handled with care.

Beth Carmichael
We recently had our basement finished by Black Bear Basements, and working with Brian was outstanding from start to finish. Our project wrapped up in early August 2026, and the entire experience exceeded expectations.
Brian managed the project from day one and was on-site almost every day to check progress and ensure top‑quality workmanship. He kept us updated with consistent progress reports and always let us know what to expect next. Communication was excellent — he answered calls, texts, and emails quickly and addressed every question or concern with patience and expertise.
His professionalism really shows, but just as important, he’s friendly, personable, and genuinely great to work with. We always felt confident that our basement was in good hands.
I would absolutely recommend Black Bear Basements — and especially Brian — to anyone looking to finish their basement. Fantastic experience all around.

Answers to Common Questions
How much does it cost to finish a basement in Denver?
Basement finishing costs vary based on the size of the space, layout, number of rooms, bathroom or wet bar additions, and the finishes you select. Black Bear Basements provides a detailed proposal after we understand your space, goals and design preferences so you know what to expect before construction begins.
How long does it take to finish a basement?
The timeline depends on the size and complexity of the basement, permitting, material selections and the scope of work. During the proposal and preconstruction process, we provide a project schedule so you understand the expected timeline before work begins.
Do I need a permit to finish my basement?
In most Denver-area communities, finishing a basement requires building permits, and electrical, plumbing or mechanical work may require additional approvals and inspections. Black Bear Basements coordinates the permitting process as part of preparing your project for construction.
